FLEMING, FPORTLAND, OREGON DRAIN FIXTURE Application filed November My inventionrelates to drain fixtures especially adapted for roofs of the so calledsawtooth design.

The saw-tooth roof design, as well known,

comprises parallel sections, vertical on one side and sloping on theother, in order to obtain increased roofing area and provide verticalglassed in surfaces arranged to receive the direct rays of the sun andthus obtain a maximum of sunlight and ventilation for a given amount offioor space.

In such construction the problem of economically and efficientlydraining the valleys between the saw-tooth sections arises.

saw-tooth sections a degree angle of slope, it is sometimes desirable toconstruct the sections on a steeper or flatter angle, thus requir- 2oing especially made drain fixtures to fit the lven angle, which at thesame time, must rain the moisture from the bottom of each valley, sothat no pools of water will collect to the damage of the roof.

Therefore the object of my invention is to provide a simple andeconomical drain fixture adaptable for draining the valleys of asawtooth roof of any given angle of slope without alteration oradjustment and capable of so being connected to the usual arrangement ofdrain pipes regardless of the angular arrangement of the drain fixturesand the slope of the saw-tooth sections.

Another object of my invention is to provide a drain fixture of thischaracter, adapted to lie flush in the bottom of the valley between.

the saw-tooth sections, so that no moisture will collect therein inpools on the roofing material with which the roof is covered.

A further object of my invention is to provide a drain fixture adaptedto efiect a moisture proof seal at its rim with the water proof ingmembrane of the roof.

To this end I provide a drain fixture com- 4 prising abasin-body havingopposite sides making an acute angle with each other, one

side being of greater height than the other,

the basin-body open at the top and the plane touched by the rim thereofmaking an acute; 4 angle with the higher of the said sides, the,

Fig. 6 shows a fragmentary side view of a saw-toothsectionconstructedwith a steeper Fig. 5 shows a section taken on theline 55 angle of slope than in Fig. 4, and illustrates" how my drainfixtures are installed Without alteration to the construction of thebuilding.

I With reference to the figures, my drain fix- 'ture comprises abasin-body a provided with open'at the ends and'threaded as at b toreceive suitable drain connections.

The side walls 0, (Z of the body member. a 3 form an acuteangle witheach other, and the side wall (Z is of-lesser height than the side wall"0 and-is a plane surface, the sidewall 0 being curved to meet the planesurface of the wall cl, thus forming in aplan View an oval with onestraight side formed by the walld, as shown in Fig. 1. e r i The planeof the rim of the basin-body a forms an acute angle with the higher side0 of the basin-bodyto conform to the angle of slope of the saw-toothsection tow-hich it is a cylindrical cavity 6 in its bottom, which isattached, and is provided with an outwardly and upwardly flaring flange6.

Rest lugs f and sockets g are formed in the interior of the basin-bodyadjacent the rim which respectively supports and forms a hingedconnection for a grille plate h, which lies in a plane parallel to thesaid plane of the run.

A clamping ring '11 is provided adapted to be seated on the flange e andto have a roofing membrane 2 clamped between. The ring 71 is providedwith threaded sockets j arranged to register with companion threadedsockets 7c in the flange and to receive bolts Z, by which the clampingring is closely secured to the said'flange.

The axis of the sockets j and k are parallel, so that the clampingstrain of the bolts will all be in the same direction and will not tendto disrupt the clamping ring or flange when tightly threaded into place.

Suitable means, such as exterior lugs m are provided about thebasin-body for supporting the drainage fixture on the roof structure 3.

Asillustrated in Figs. 4: and 5, my drainage fixture is adaptable tosaw-tooth sections of any angle by merely rotating the fixture on thelongitudinal axis of the cylindrical cavity 1); in other Words by merelyplacing the fixture in the cut-out port on prepared in the roofstructure to receive the drain fixture, the center line or axis of thecavity b'will lie in the same straight line and the alinement of theconnecting drain pipe n with other drains in the same valley will not bedisturbed as shown in Figs. 5 and'6.

To further illustrate how my drain fixture I is thus adjustable tosaw-tooth roof sections of varying degrees of slope, in Fig. 4:, isshown my drain fixture installed inthe sawtooth roofs of 30 degreesslope, and in Fig. 6, I have shown diagrammatically asimilar fixtureinstalled on a 45 degree slope.

Figs. 2 and 4 also illustrate how my drain fixture is arranged to lieflush in the bottom' of the valley so as to efficiently drain the sameand form a moisture proofseal with the roofing membrane. In the form ofroof construction illustrated here, a layer of plastic material 4 hasbeen laid over the roof struc-- ture and the flange e is laid flush inthe said plastic material, so that the roofing membrane 2 as arrangedbetween the flange e and the clamping ring 2', is slightly above thelevel of the plane of the rim of the drain fixture, and since theclamping ring 2' is contained flush within the flange e, no moisturewill collect about the drain. but will tendto run into it and be carriedoil.

I claim:

A drain fixture comprising a basin-body having opposite sides making anacute angle with each other, one side being of greater height than theother, the interior face of theing material.
